Device for transmitting a rotational movement, of the speed- reduction type, and motorised articulation making use thereof

摘要

The invention relates to a device for transmitting rotational movement of the speed-reduction type comprising a ring gear 7 with internal teeth 7 and a rotating member 1 in the form of a barrel with helical threading arranged inside the toothed ring gear 2 so as to mesh with the latter, the rotation axes of the ring gear 2 and of the rotating member 1 being orthogonal and non-concurrent. <IMAGE>
